"I'm sure one of them is on parole."
Not yet, Nephew still has to stand trial for punching out The Dirtbag (Father of Niece's twins).
Despite that, his mother got him to drop HIS complaint against Niece, for running him over.
Some day, hopefully, he will learn about leverage.
For what it's worth, Niece actually drove Nephew over to punch out The Dirtbag.
